Hi Herb,

Try melting and re-flowing the solder on each of the solder pads, one lead at a time for each component, then recheck your voltages. Before doing this to the torroid coil windings, measure their resistances first with an ohm meter. You might have a cold solder joint on one or more of these coil wires, due to the fact that there is transparent enamel insulation around these wires. You undoubtedly carefully scraped off this enamel insulation, but it could be deceptive. It is possible that solder flowed around, but did not stick properly to the wires. I had this happen and had to re-solder mine as such. Visual examination did not reveal the problem, so I carefully tinned the wires and when this appeared ok, I re-soldered the coil back on to the board. This time I had success, and my set worked.

Keep us up to date on your attempts to get your receiver going. Hope you get yours up and running soon.

"I even removed L1 and reversed it"
Be sure to put the toroid back as shown in the build manual.  If the "sense" for the one-turn tickler is wrong the regeneration won't.  So trying to correct low volume through the speaker, changing L1 may have produced lots of hiss in the headphones but no RF gain ( regeneration ).  Also, a gimmick of about 1" twist was good for me using the station antenna.

BTW, whoever designed and kitted this radio did a first class job, this regen receiver worked right off of the build table, unlike some others I have built.  Especially if the description has "high performance" in the name, I had poor results.  Like my dear old Dad always said, better to under promise and over perform than the other way around.

Thanks for the review of the stories.
The TinyCat Library is getting pretty full now.
i have to limit the total number of books because of the scrolling banner.
It is taking 3 minutes right now to scroll through all the books.
i could add hundreds of book in a tabular list without a scrolling banner.

Have you tried the radio with headphones?  The volume available from the speaker without more amplification is underwhelming.  I added one of those cheap $2 amplifiers to increase the volume through the speaker.

Thanks! I'll check it out when I get back, the 1st week in June.

You don’t get much volume at all out of the speaker. Yes headphones. And try a couple of different ones if you have them. I also added an audio amplifier.
